SPECIFICATION forming part of Letters Patent No. 422,215, dated February 25, 1890.

v Application filed September 18, 1889- Serial No. 324,323. (No model.)

To all whom it may concern:

Be it known that I, CHARLES M. HINE, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Double-Plaiter Machines; and I do hereby declare the following to be a full, clear, and exact description of i the invention, suchas will enable others skilled 5 and 6 are side views of the cams.

in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this sp'ecification.

My invention relates to an improvement in double-plaiting machines; and it consists in the combination and arrangement. of parts, which will be more fully described hereinafter, and especially pointed out in the claims.'

The objects of myinvention are to produce a double-plaiter machine of the special construction hereinafter described, and illustrated in the accompanying drawings, which enables the distance between the stitching mechanisms and plaiting mechanisms to be varied at will, according to the width of the material being plaited, to regulate the move-- plished.

Figure 1 is a perspective of a machine which embodies my invention complete. Fig. 2 is a a cross-section taken through Fig. 1 on the dotted line a: as, looking toward the rigid casting. Fig. 3 is a similar view taken on the dotted line 4 y, looking toward the rigid cast- 1 45 ing from the reverse side. Fig. 4 is a plan view of the under side of the machine. Figs. Fig. 7 is an edge view of the'cams. Fig. 8 is a perspective of the gearing and feeding cams. Fig. 9 is an inverted perspective of the loopershaft and the bearing therefor. 10 is a G" and F, the shafts W and G, and the hook D A represents the base of the machine, upon the top of which rests the horizontal base anisrns hereinafter described are supported and journaled. This horizontal plate B is pivoted to the upper ends of the vertical supports which rise upward from the ends of the base A, near its rear side, as shown, and

turned upward for the purpose of giving ready and easy access to the mechanism secured to its under side. Extending upward from each end of this plate B, near its rear side, are the vertical main supports D, be-

any suitable manner. Also extending from this plate B, inside of the supports D, are the castings F F, and which are preferably of the peculiar shape here shown, for the purpose of forming bearings for the sliding plaiter-rcds, the needle-bars, and the presserbars. 1

The horizontal beam E is provided with a longitudinal groove G, preferably U-shaped,

H is placed, and which shaft is supported at each end by conical adjustable bearings formed by the screws I, which pass through the supports D and into conical cavities formed in the ends of the shaft. Secured to this shaft is a sleeve J, which carries an arm K, that projects outward through the groove in the beam and has pivoted to its outer end a needle-bar socket L. This arm is moved back and forth by having the sleeve J slide easily upon the shaft H, andis oscillated with said shaft by providing the sleeve with an inwardly-extending projection that fits and slides in the longitudinal groove M made in the shaft. Also made in the horizontal beam F. is a transverse groove N, in which the upright slotted lever 0 moves as it is oscillated by the operating-shaft H, to which it is attached. A second arm P, similar to the arm K, is secured to the shaft H at the right-hand side of the machine, and which also carries detached vertical section showing the gears plate B, upon which and to which the mechtween which the horizontal beam E is held in as shown, and in which the oscillating shaft which enables the horizontal plate to be v rigidly attached to the horizontal plate B,

while the casting F at the left of the machine is moved back' and forth upon the plate for the purpose of adjusting it nearer to or farther from the plaiting and stitching mechanism placed at the opposite end of the machine. 7

Made in the plate 13 are the longitudinal slots S, through which pass the screws T, Fig. 4:, which screw into the base of the cas 1:- ing F, and by means of which the casting is readily adjusted and securely held in its adjusted position. Also made in this plate B is a longitudinal slot U, in which the feeder V v and needle-plate move back and forth with the casting F and the mechanism which is attached thereto.

WV indicates the main operating-shaft,which is 'journaled to the under side of the plate B in the bearings X, which are secured to the opposite ends of said plate, and to the outer extending end of which shaft is secured the ordinary band-operating wheel Y, and between this wheeland the plate upon said shaft is the eccentric Z. The pitman A is provided with a sleeve at its lower end that surrounds the eccentric Z, and has its upper end pivoted to'the outer end of the lever B, which has its inner end secured to the oscillating shaft H, and by means of which said shaft is oscillated through the medium of the main shaft and the cam Z secured thereto.

Extending outward and upward from the castings F F are the supporting-arms G, in which is j ournaled the plaiter-operating shaft D, which extends parallel with the beam E and the oscillating shaft H, which is placed therein. Secured upon this plaiter-operating shaft D isaratchet-wheel E. Placed loosely upon this shaft is an oscillating sleeve d, which is provided with a socket efor the reception of the vertical arm Gand a set-screw for securing the said arm at any desired adj ustment.

Pivoted between arms secured to or formed upon the upper end of the rod- G is the connecting rod or arm H, which has its opposite end pivoted upon a screw-threaded pin 1', which moves back and forth in the slot made in the upper end. of the oscillating arm 0. Also secured to the downwardly-projecting arm I v of the sleeve cl is the spring-actuated pawl J, which engages the ratchet-wheel E, secured upon the shaft D.

Placed upon each end of the plaiter-operating shaft D, outside of its bearings, are the two cams K L, which engage the hardened surfaces M of the pivoted operating-levers N, which have their upper ends pivoted in the arms X, extending outward from the sleeves R. The lower ends of these levers N are loosely connected to the sockets P ,which are secured, respectively, to the sliding rods or bars Q, which have their bearings in the bases of the castings F F. Attached to the rear ends of these sliding rods Q are upwardly projecting guiding arms P, which have their upper ends engaging horizontal grooves made in the horizontal arms R,which extend outward from the sleeves R. The ob-' ject of these guiding arms P is to secure the sliding rods Q in their proper position and prevent them from having any turning or oscillating movement whatever. Secured upon the opposite ends of these sliding rods Q are the hangers S ,which carry the plaiter-blades, and which have their inner ends provided with a socket and a set-screw, by means of which they are secured to the said rods and either adjusted back and forth thereon or entirely removed to allow the plaiter -blades to be sharpened, or to have others containing different-shaped plaiter-blades secured in their stead.

For the purpose of returning the levers N to their original position after they have been operated upon by the cams K L the springs T are provided, and which have their ends secured, respectively, to the sleeves R and the said levers. The movement of the lower ends of the levers N is adjusted by means of the endwise-moving stop-rods U which passthrough the base or feet of the castings F F, and are held in their adjusted position by means of set-screws, and which rods engage the lower ends of the levers. The plaiter-blades V have their outer ends rigidly attached to the outer ends of the hangersin any desired manner.

WV indicates the needle-bars, which pass vertically through arms X, formed upon the castings F F, and which arms also form aw NW ings for the presser-bars Y. Secured to the main shaft W arethe feederoperating cams Z, which as the main shaft revolves engage a downwardly projecting arm 1" of;the feeder V and which, together with the springs A, impartto the feeder upand-down and back-and-forth motions, thus feeding the material which is being plaited. The speed at which the material is fed is regulated by the adj listing-screw B which has its inner end engaging downwardly-projecting pins f, secured to the feeder V The bearings 25 for the adjustable feeder are supported independent of the horizontal bedplate B, and are engaged by or connected to the adjustable casting F, so that when this casting and the stitching mechanism are moved nearer to the casting F- the feeder is moved with it.

Journaled in castings a h under the horizontal bed-plate, just above the main drivingshaft, are small supplementary shafts to which are secured the hooks or loopers D, as shown in Fig. 2. Also secured upon these supplementary shafts O" are the cog-wheels F, which engage the cog-Wheels G,'secnred .to the main shaft below the cog-wheels F.

- lution of the plaiter-operating shaft D relative to the oscillations of the shaft His regulated by means of the adjustable pin 1 and the adjustable bar G. When it is desired to increase the speed of this shaft D, the rod G is lowered in the socket of the sleeve F and the pin 1 moved upward in the slot formed in the oscillating lever 0. Should it be desired to decrease the revolution of this shaft D the rod G is raised and the pin I lowered, which shortens the distance of the pin I from the center of the oscillating shaft, thus shortening the distance traveled by said pin, and lengthens the distance of the upper end of the rod G from the center of the shaft D,

' thus decreasing the number of teeth engaged slide along upon it to any required distanceat the same time that the upper portion of the stitching mechanism and plaiting device is moved, they being attached thereto by screws through the slots in the bed-plate.

order to prevent the operatingshaft D from having any backward movement as the pawl Jj moves backward over the ratchetwheel E or from any pressure of the levers on the cams, a brake L is provided, which consists of a vertical standard extending upthe shaft D.

ward from the base-plate B and surrounding Passing'through this standard, which is provided with a slit of suitable length below the shaft D is a screw, by means to the width of the material which is being plaited; v A

The cams K are secured to the operatingshaft D, while the cams L are loosely placed upon the sh aft and provided with a circular slot 1', through whichpasses the securing-screw J; By means of this construction these two cams can be quickly and readily adjusted in relation to each other so as to give the sliding. bars and the plaiter-blades secured therer to any desired movement in relation to each other. The style of the plaitcan also be varied by causing the plaiter-blades at one of the stitch-forming mechanisms to travel farther than the other, or at a different period of time from the other, thus laying the plaits on each side alternate one to the other, or both in the same direction or in a reverse direction, or to make one side of the plait wider than the other. This construction also enables the stitch-forming mechanism and the plaiting mechanism at the left hand of the plaiting mechanism without in any manner interfering with the operation of the machine. V i

While I here show one form of cams for operating upon the pivoted'levers-I do not limitmyself' to this particular form,'for it may be varied and a-cam of any desired shape placed in its stead, These cams being adj ustable upon the shaft and adjustable in relation to each other, they may be so arranged as to operate alternately or in unison, or the blades of each separate pair'be-operated alternately or in unison with a like blade in the other pair. These adjustments also permit the forming of a boX-plait, right-hand side plaits, or left-hand side plaits oneither or both edges of a fabric at the same time.

Having thus described my invention, 1'
